The Leonardite Preparation Unit planned for the Humic Acid Production Plant screens run-of-mine leonardite, weighs the required quantity and feeds it into the reactor in a controlled manner. The material is classified on a screen with 8 mm openings; undersize leonardite is collected in a weighing hopper in operator-adjustable quantities and transferred to the reactor.
